Patented Uct. 7, 119113.

Application filed June 15, 1910. Serial No. 567,050.

T0 all whom I? may concern Be it known that I, ROBERTL. COONEY, acitizen of the United States, residing at Atlanta, in the county ofFulton and State of Georgia, have invented new and useful Improvementsin Stationary Fire-Extinguisher Systems, of which the following is aspecification.

The present invention .is an improvement in stationary iire extinguishersystems and it involves certain novel features of myconstruction,arrangement and operation, conof reference designate whichI am the originator and which, forming the bases of co-pendingapplications, Serial `Numbers .540,661 and 530,470, need only bedescribed in a general way. In the eX- ample illustrated, the systemincludes a sta- 'tionarv chemical mixing tank, as 1, containing an acidbottle, as 2, and a distributing pipe, as 3, which leads from the tankand as 4, which projects there-- into. The tank is partially filled withan alkaline solution and the bottle 2 is mounted for inverting movement,being piyoted off center upon a'bracket 5.

With the mode of operation described in the applications aforesaid it isessential to provide for the maintenance of the pressures at equaldegrees and for this purpose the pressures are normally in communicationthrough a by-pass pipe, ras 6, which may .have a capillary bore or whichmay be, as shown, provided with a diaphragm 7,

having an aperture of pin-hole diameter.

The extension 4 and the pipe 3 are constructed to afford an enlargedchamber, as 8, which is preferably located above the solution level andwhich ineloses a ball, as 9. The lat-ter is, in' e'ect, a valve, andnormally closes ,the mouth of the extension 4 which communicates withthe chamber 8.

-.The ball 9.l is weighted to some exten-t for a purpose which willpresently appear and is prevented from closing against the end `of posedguide Jinsufficient to ,the ball through the intermediary of the' thepipe 3, in communication with the ch amber 8, by a perforated web, asl10, which bridges said chamber.

At one side of the chamber 8, a float chamber, as 11, is provided. Theupperend of the chamber 11 is open and in communication with the tank.The lower end of the chamber 11 is provided with anI opening, as 12,having its wall formed as a valve seat and in communication with apassage, as 13,

afforded by a connection which extends downwardly from the chamber 8 tothe chamber 11. W'ithin the chamber 11 is a float, as 14 having atits'lower end a valve boss-15, which, in the operation of the sys-l tem,closes against the wall. of the opening 12. The float 14 surrounds anaxially dis.-

stem, 4as 14a and is held in a normal position by a body of liquid,-as16, which partially fills the chambers 8 and 11 and which is shiftableconsequent to the .pneumatic impulse aforesaid but which is naturally atrest in its normal position. This body of lliquid is the equivalent of amechanical element end is to be -so considered. The movement of thefioat 14 is consequentto the shifting of the body of liquid -16 and theoperation of the system is direct-ly consequentY to the movement of thefloat. An advantageous means for eilectuating this result consists' of alever 17, which is pivotedbetween its ends onI a bracket 18 and whichhas one end pivotally associated with the loat and its other end inlatching engagement with a lug, as 19, which is provided at one side ofthe acid bottle.

From the foregoing description it will be readily apparent that when thebody of liquid 16- is shifted so that its level in the chamber 8 islowered, the float 14 will descend and in such movement will rock thelever 17 and release the acid bottle 2. The latter thereupon `invertsand discharges its contents intothe body of solution... The developedhigh pressure forces the solution from the tank and of course producesthe displacement of the ball 9 and also acts on t-he doat to cause thevalve boss 15 to seal the opening 12,v in order that there may be noappreciable escape of pressure therethrough in advance of the out-goingcolumn of liquid. The organization is of such nature that the operationmay' be produced with an impulse of exceedingly light character andproduce the displacement of instantly,

pulse but,

intervening body of solution. The -organi- 1zation is furthermore ofsuch nature that it Having Jfully described my invention, I
